PROBLEM TO BE SOLVED: To provide a vibration generator which provides large amplitude vibration by using a simple constitution and whose size and weight are easily reduced. SOLUTION: The generator has a plurality of piezoelectric vibrators 1. On each of the vibrators 1, a piezoelectric element 4 is pasted on at least one of the surfaces of a vibrating plate 3. The tip sections of the vibrators 1 are linked together on a link plate 5 while the vibrators 1 are laminated. Thus, the amplitude of the entire laminated vibrators 1 becomes close to the total sum of the amplitudes of respective vibrators 1. Thus, large vibration is obtained by employing an extremely simple constitution without using a weight and the size and the weight are easily reduced. Moreover, practically no variation exists in the vibration characteristics. Therefore, tone quality and volume do not vary substantially even though incoming coll vibration and conversation voice are simultaneously generated.
